The Zoogeographic Composition of the Insect Fauna (Odonata, Coleoptera, Macrolepidoptera) in the Raised Bogs of the Belarusian Lakeland

Abstract

The zoogeographic composition of insects in the raised bogs of the Belarusian Lakeland was investigated. The oundaries of this region coincide with those of the last glaciation and the distribution of raised bogs on the East European Plain. By the example of three model groups (Odonata, Coleoptera, and Macrolepidoptera) it was found that the insect fauna complexes in the bogs of the Belarusian Lakeland had a typical boreal pattern with prevalence of species with Euro-Siberian ranges, and also included large fractions of species with Circumboreal and Circum-Arctoboreal ranges. The environmental conditions of bogs in the temperate zone of Europe facilitate the southward expansion of many cold-adapted species.
